Legend Valve 416-392 reducing coupling
The Legend Valve 416-392 is a stainless steel reducing coupling designed to connect pipes of different diameters in industrial plumbing systems. It features FNPT x FNPT threaded connections for secure joining and is constructed from 316 stainless steel for corrosion resistance. This new fitting meets applicable industry standards for specified pressure and temperature ranges.
Pressure performance across temperature ranges
The coupling is rated for 290 psi from -4°F to 100°F, 239 psi at 212°F and 218 psi at 302°F. These ratings show how the maximum allowable pressure decreases as the operating temperature increases. The fitting is engineered to maintain integrity within these specified limits for sustained operation in demanding environments.
2 inch by 1-1/2 inch FNPT connection size
The coupling connects a 2 inch pipe to a 1-1/2 inch pipe using female National Pipe Thread tapered connections on both ends. This specific size determines whether the fitting matches the piping system you are assembling. Verify your pipe dimensions before ordering to ensure compatibility.

Questions about this item
Will the 316 stainless steel coupling run hot or make noise under continuous 218 psi at 302°F?
The fitting is a passive component with no moving parts, so it generates no noise and adds negligible heat beyond the fluid temperature.
What pipe threads must I already have to install this FNPT x FNPT reducing coupling?
You need a 2 inch FNPT threaded pipe on one side and a 1-1/2 inch FNPT threaded pipe on the other for a direct connection.
Can this 316 stainless steel reducer join older carbon-steel pipe without galvanic issues?
316 stainless is more noble than carbon steel; in conductive fluids a dielectric union or isolation kit is recommended to prevent accelerated corrosion of the steel pipe.
